Column Swap (mb)
Source /usr/bin/vmstat 1 11
Description
Calculates the last 10 samples from a vmstat command. We sum the fourth column of vmstat (swap), average it, and then divide by 1000000 to convert it to megabytes.
  • NO_SWAP BLINKING RED : 00.0mb <= swap < 4.0mb
  • SWAP_LOW RED : 4.0 <= swap < 10.0mb
  • SWAP_LOW AMBER : 10.0mb <= swap < 50.0mb
  • SWAP_OK GREEN : 50.0mb <= swap <= 200.0mb
  • SWAP_WASTE WHITE : swap >= 200.0mb
